How to make a sandblast with your own hands?

For today in shops the huge choice of sandblasting devices possessing various funktsionalom and cost is presented. However, the whole problem lies in the fact that reliable and high-quality equipment of foreign production is quite expensive, and their domestic and Chinese counterparts very quickly fail. Therefore, many people are interested in the question: "How to make a sandblast with their own hands at home?"

In practice, there is nothing complicated. If you have everything you need, you can do the sandblasting machine yourself, and the entire production process will take only a few hours. The most important thing is always to follow certain instructions and safety procedures.

How does the sandblaster work?

If you are thinking about how to make sandblasters at home, then before you go directly to the matter, you must first turn to the theory and understand its principle of work. By and large, it's pretty simple. Through a special nozzle under high pressure air is passed, which captures with itself an abrasive material.

What will be required for the manufacture of equipment?

In the sandblasting process you will need the following parts:

• High power compressor;
• Capacity of a special shape and a 45-degree angle of the walls, which will serve as a reservoir for the supply of abrasive material - the gas cylinder is best suited;
• Reinforced rubber hose;
• Ball valves S 111;
• nozzle;
• Two small pieces of steel pipe with a diameter of 5 centimeters;
• Gas sleeve length of 5 meters;
• Fittings;
• Collet clamps;
• Adapters and plugs for pipes;
• Fum-tape.

All these components can be found in specialized stores, and their purchase will cost about 2000 rubles, but what about the nozzle? It can be ordered from the US, however, when buying, you should pay great attention to the material from which it is made. The ideal version will be a carbide nozzle, since such a product has high performance characteristics. Also it can be made independently from a spark plug. Do not know how to make a nozzle for sandblasting from a candle? Simply dismantle the main part of the candle, and use the body as a nozzle.

Preparatory stage

First of all, you need to prepare all the components that are necessary for making sand blasters. As a container for sand, it is better to use a gas cylinder, because it has high strength and is able to withstand high pressures. It is possible to use cylinders both from freon and from propane, but in the second case, before starting preparation for installation, it is necessary to completely pump out gas from it, in order to avoid possible ignition and explosion during welding operations. Compliance with safety regulations is one of the important aspects in the sandblasting process.

When the issue with the container is solved, purchase all the other components and prepare the nozzle. If everything you already need is at your fingertips, then you can proceed to the next stage of the answer to the question of how to make sandblast your own hands.

The process of manufacturing the apparatus for sandblasting

Making a sandblasting machine is not a very difficult process, so if you have at least some technical skills, then there will not be any special problems. So, how do you make sandblast yourself? All works are performed according to the following instructions:

1. In a gas cylinder at one level, two five-centimeter holes are made, one of which must be strictly in the center of the bottom, and the second - in place of the crane. To the top hole is welded a piece of pipe, which will serve as the neck.
2. The second opening, located at the bottom of the cylinder, is welded to the second section. It will serve as a sink for abrasive material. When performing welding work, it must be ensured that everything is very tight.
3. When the welding work is completed, you can proceed with the installation of components. On both outputs are installed cranes, for greater tightness which is used by a tape tape.
4. On the tee, fittings are installed, on which the hoses are screwed.

This is the main part of the work coming to an end and you can proceed to the final stage.

Assembling the sandblaster

The answer to the question of how to make sandblast for candles, comes to its logical conclusion, and you will only have to assemble the apparatus into a single whole. To do this, it is necessary to attach a hose with a diameter of 14 millimeters, located on the abrasive material tank, and fix it with a clamp. At the other end of the hose is inserted a purchase or self-made nozzle. To make it dead and not fall out during work, it is fixed with a collet clamp.

A simpler version of the sandblasting machine

The above method of making a sandblast seemed to you very difficult and troublesome? And you want to know how to make sandblast at home easier? There is another version of the manufacture of equipment with a simpler design, which is perfect for performing easy cleaning of various surfaces. To do this you will need a tee, a ball valve and an ordinary bottle of soda.

How to make sandblast from these materials? The first thing to do is to empty the hull of the spray gun so that a nozzle can be installed in it. Then, the handle and the fittings are attached to it. That's actually the whole process of making a device for sandblasting a simplified design, which takes no more than an hour of your time.

The disadvantage of such a device is that during its operation, there is a very rapid wear of the parts, so if it is used frequently it will be necessary to replace them regularly. Otherwise, as the diameter of the nozzle increases, the level of productivity and cleaning efficiency will be significantly reduced. On average, such a device will be enough for about half an hour of work.

Types of apparatus for sandblasting

So, you already have a detailed idea of how to make sandblast yourself, so it's time to talk about what kinds of equipment exist for today. On the type of equipment depends not only functionality, but also the scope of application, as well as design features. Nowadays there are the following varieties of sandblasters:

1. Suction - have low productivity, so their main field of application is to perform cleaning works of small complexity.
2. Vacuum - have a cyclic operation principle and allow you to reuse abrasive material.
3. Pneumatic - have a high productivity and a long service life, therefore they are used on an industrial scale to clean large areas or contaminations of increased complexity. If you are interested in how to make sandblasters of this type yourself, then immediately it is worth saying that this idea is not the most reasonable. The thing is that this device is connected with very high power and high pressure, the work with which can be dangerous for life.

In addition to the basic classification, all sandstones can be divided into two groups, depending on the way the sand is fed - pressure and injector. In the first, the supply of sand is carried out both in the apparatus and in the tank, and in the second - only in the apparatus itself.

Advantages and disadvantages of self-made sandblasters

If we are already talking about how to make sandblast at home, then we need to talk about the advantages and disadvantages that they have. The main advantages are the following:

• Simplicity of construction and speed of assembly;
• Cheapness of production;
• Relatively good reliability and durability.

Nevertheless, there were some shortcomings, which should also be taken into account:

• To assemble the device yourself will not work if you do not have similar work experience;
• Sandstone, constructed from cheap materials, will not last very long;
• If a low-quality nozzle is used, the cleaning result will be appropriate;
• If any mistakes are made during the assembly process, the risk of injury when working with the device is significantly increased;
• Homemade sandblasting machines significantly lose their factory reliability and functionality.

Considering all the advantages and disadvantages of this equipment, it is recommended to think carefully and make a well-considered decision before starting to manufacture it. In fact, there is nothing serious. If you follow the instructions, then everything will turn out.

General tips and advice on working with sandblasters

When operating the sandblasting unit, especially for home-made appliances, it is very important to observe all safety precautions and safety rules. It is best to allocate a separate room for the operation of this equipment. In the process of sandblasting, the use of face masks and other means of protection of various parts of the body and the respiratory tract is mandatory. In addition, your body must be completely covered with clothing.
